+If you reduce msec to 3, Trac will work as it should. The problem is, sqlite cannot create temp files in /tmp at msec 5 because /tmp is set to 1733. I tried to work around this by giving apache rwx privileges on /tmp by using acl like so:
+
+{{{
+setfacl -m u:apache:rwx /tmp
+}}}
+
+That worked until the next time msec swept through the filesystems and reset the permissions back to what they were defined to be in /usr/share/msec/perm.5 .
+
+That would change the acl mask, which would, once again, result in Trac raising errors like the one above. The solution, as imperfect as it is, is to create a file /etc/security/msec/perm.local into which the following should be entered.
+
+{{{
+/tmp/   root.root       1777
+}}}
+
+This specifies an exception to the default permissions defined in /usr/share/msec/perm.5, which prevents msec from changing the permissions on /tmp as it periodically sweeps through the filesystem.
